In Battlefield 4, we are getting 6.92A and 7.10A with OC (called "Uber" mode in the review). Witcher 3 goes even higher with 7.79A. This stress is not expected on all motherboards.
EDIT: If you take a look at the graph, you'll see in Witcher it actually pulls near 200W in Uber Mode.
Thank you! After reading and translating the review a few things are made clear.
The uber mode is the boost clocks (1266 mhz) and not an overclock per se. Not good then, since it does draws more than what the pcie standard calls for.
Second, there could be a possibility that your mobos pcie could get fried if it's not a nice mobo. Hmmm...
I'm assuming the AIBs will have more sense and use 2 x 6 pins or at least an 8 pin to mitigate this. I guess we'll have to wait for those.
I wonder what AMD will do to sort out the reference design? Send out new drivers that lower performance to hit the pcie specs? This will probably affect those buyers that are budget conscious and will buy the reference over spending more... Hopefully they fix it since AMD needs to do good in this segment.Edited by mark_thaddeus - 6/29/16 at 8:48pm
